Application filed December 22, 1926.

"this invention ri-vlates to means for inountion; the spindles for loom pickers and it the general oliiject oi? the invention to provide a very simple lllOUlilllllg' wherein the inner and outer ends of the spindle may be held tightly with respect to the lay and any wear taken up by means of? a single adjustinp; nicinl'ieix in be: looms and on the plain ends 0t some \VMAJL/ replenishing; looms, the propelling torco tor the shuttle is transmitted from the picker stick througirh a so-cnlled piclrer which slides along a cylindrical ride known as the.

ndle. Experience.shows that the spin-- die due to constant vibration oi; the picking; motion, is subject to wear and hcconiics loose and it is an important object of my present invention to provide means for taking: up any resultant ioosencss at looth ends of the spindle by a sing rn'ieana in, co-pendingr application :ttl55fl'd-il filed by Parent there is shown a clamping; member having split portions and inclined surfaces so related that the spindle will be held tightly lay the split part of the support when the latter is moved relatively to listed inclined surfaces, this mode ct support being; employed for the inner end oi the spindle. In latent rltlfiQ-ldifitl granted to Lanoiault there is shown a screw in line with the axis of the spindle and threaded into a fined portion of the lay, said screw being-movable to take up wear on the ends of the spindle.

it is a further object of my invention to combine the structures shown in said application and said patent and employ the screw r-shown in the lianciault cinistroction tor comp on; the split portions oil: the clainpinn' element shown in the Parent applicatioiii to the end that said screw may he edectire to hold both ends of the spindle th there and othru' objects which will appear is the deaoription procoeds my invcntirm relates to the :o'rangcinento comhinations oil? parts heli'eina'ttci. set liorlh, and more particularly pointed out in the claims.

Fig. 3 is an enlarged vertical section on line (i- 3 oi? Fig. 1, parts lacing removed tor the salts of clcarncss, and

Fig. at is a vertical transverse section on line itl ot 1i" 3 Referring; to

the drawings the lay 1O provided. with a lay end 1.]. and lay sword l2 and may be provided with lJOlI guides 13. Eihuttlc boxes 14L accommodate shuttles E3 and may be moved vertically by mechanism not shown, that either shuttle may become active. A. spindle 1.5 has slidably mounted thereon picher 16 provided with a shuttle engaging portion 1? and having onith picker eticlt 18. During each pic i of the 100m when the lay is substantially on top center the picker stick will be moved to the right from the position shown in 1 and 2 to picl: the shuttle through the shed, the picker moving; along; and being chided by the spindle This part oi the con struction is very old and forms no partoiii my present 1 nven ti on.

The support tor the outer end of the spindle is identical with that shown in the aforesaid Lanciault patent the lay having a threaded bore 20 formed in a block 21 cared to the lay end. The spindle 15 projects into one end of the bore 20 and the holding screw 22 is threaded into the other end oisaid bore, a lock not 23 being employcd to check accidental movement of screw 22. The latter is in tight contact with the left hand end of the spindle 15 and is the means by which longitudinal movement of the spindle may he effected. The spindle is inserted through the here 21 when being assembled and may be withdrawn through said here lay the remote-l ott screw 52%.

The inner end of the spindle supported by mechanism similar to that shmvn in the aforesaid Parent application and employs the usual his; custoina v cast int gral with layend ll. itiaidlugha a here a potion ot which is cylindrical as indicated at 3 t, and a portion. of which is conical as at it elai'nping member do ignatcd ierally at :3 has; a cylindrical bore Set of suhstaiiitially the same diameter as the external diameter of the spindle 15, and the member 33 is pro vided with an exterior conical surface 35 which is in contact with the interior conical surface 3:2 oi lug That portion of the cl mpinp; member adjacent to the bore lll split as indicated at 36 to provide said fill lUU

clamping member with a plurality of resilient elements 37 which are movable inde pendently of each other and compressible to vary the diameter of bore 34-.

In assembling the device the spindle, which may have both ends thereof square as indicated in the drawings and without the customary taper on one end, is inserted through the bore 20, as previously described, and into the cylindrical bore 3i of the clamping member 3 The screw 22 is then threaded into the bore 20 and forced against the left hand end of the spindle 15. This moves the right end of the spindle t0 the right hand end of the bore. 34 into engagement with the t'olid portion of the clamp 33. The latter is, therefore, moved slightly relatively to the lug and the cooperating inclined surfaces and co-aet to compress the elements 37 against the right hand. end of the spindle 15. \Vhen both ends of the spindle have been made sufliciently tight, the check nut may 7 be positioned as shown in Fig. 3 to prevent accidental movement either of the screw 22 or the clamp 33.

From the foregoing it will be seen that I have provided a very simple means for securing both ends of the picker spindle with respect to the lay, the spindle being formed with square ends and being free from the customary conical tip usually provided on the inner ends of the spindles. It will be seen that the screw 22 serves not only to prevent displacement of the spindle to the left, but is also the means by which the clamping member is forced into close holding'engagem'ent with the spindle.

Having thus described my invention it will be apparent that changes and modifications may be made therein by those skilled in the art without departing from the spirit bore to receive one end of the spindle, a plurality of independently movable and slightly compressible elements formed with the member and lying around the bore, and a screw threaded into a part of the lay and engaging the other end of the spindle and capable of moving the said spindle in a direction toward the member to cause said inclined surfaces to force the slightlv compressible elcments against the spindle and hold the same, said screw thereby preventing loosening of both ends of the spindle.

2. In a loom having a lay provided with an opening having inclined sides, a spindle clamp extending into the opening and having the outer surface thereof inclined to conform to the opening in the lay, said clamp having a bore therein, a. plurality of slightly resilient elements formed integrally with the clamp surrounding and defining the bore, a picker spindle having one end projecting into the bore and means acting on the other end of the spindle to force the clamp into the opening in the lay to force the elements against the spindle to hold the latter in place.

In testimony whereof I have hereunto a fixed my signature.
